Abstract
Aim/introduction
This study aims to investigate the prevalence and characteristics of diabetic symmetric sensorimotor polyneuropathy (DSPN) in patients with type 2 diabetes registered in the Japan Diabetes Complication and its Prevention Prospective (JDCP) study.
Materials and methods
In the study, 6338 patients with diabetes who had been treated by diabetes specialists were registered in 2007–2009. Of these, patients with type 2 diabetes who could be evaluated for DSPN were analyzed using t test, chi-square test, and logistic regression analyses. DSPN was diagnosed using the Simple Diagnostic Criteria for Diabetic Polyneuropathy proposed by the Diabetic Neuropathy Study Group in Japan.
Results
Of the total participants, 5451 patients (mean age 61.4 years old and duration of diabetes 10.8 years) were analyzed. Based on the criteria, 35.8% of patients were diagnosed with DSPN. The prevalence of sensory symptoms was 25.8%. The following factors increased risk for DSPN: age [odds ratio (OR) 1.57, 95% confidence intervals (CI) 1.42–1.73], duration of diabetes (OR 1.32, 95% CI 1.21–1.43), body mass index (OR 1.19, 95% CI 1.09–1.30), systolic blood pressure (OR 1.06, 95% CI 1.01–1.10), hemoglobin A1c (OR 1.15, 95% CI 1.09–1.22), biguanides (OR 1.22, 95% CI 1.06–1.39), and insulin therapy (OR 1.59, 95% CI 1.36–1.84). The following factors decreased risk for DSPN: total cholesterol (OR 0.98, 95% CI 0.96–1.00) and exercise therapy (OR 0.85, 95% CI 0.73–0.98).
Conclusions
The baseline survey clarified the prevalence and characteristics of DSPN in Japanese patients with type 2 diabetes. The survey also revealed the risk factors of DSPN.
